citizen of the United States of America. and

a resident of Anderson, county ot' Madison, and State of Indiana, have invented certain new and useful Improvements in Motor- Vehicle Gearings, of which thil following is a1 full and clear specification.

The object of this invention is to provide a simple supplemental gearing which may be applied to a motor vehicle. of the shaftdriven type and be utilized not only asa lowspeed drlve for the vehicle, but also as a means for driving auxiliary machinery or apparatus, as more full) hereinafter set forth.

In the drawing- Figure 1 is a vertical sectional View of the preferred form ot' my gearing, showin it applied to a motor vehicle of the Ford type; and

Fig. 2 is a vertical section taken at right angles to the line on which liigr. l is taken.'

In the drawing, a designates the rear end of the usual transmission case of the auto-i mobile motor for driving tho vehicle and which contains variable speed driving ini-elal anism of the usual type, the rear end of the main driven shaft of the transmission hein? illustrated at b in the drawing, this rear en( being, as usuarir provided with a squared Socket for con ectiou `l`,vith the usual propeller shaft of the Vehicle.,

Afixed to the rear end Iof the transmission case iS a. casing c, upon the rear wail of which is mounted the bearing d of the n sual universal joint e of the propeller shaft f of the vehicle. Connected to the inner or forward half of the universal joint is a short shaft g which is journaled in a ballbearing h mounted on the rear wall of the easing c. This short shaft g is provided with a squared socket in which lits the squared end c' of the forward end of the propeller shaft, and on the inner end of the short shaft g is carried a gear j. This gear j meshes at all times with a gear 7c aixed to a horizontal counter shaft l which carries at its forward end another-gear m.

Extending from the transmission shaft b to the short shaft g is an intermediate short shaftY n, the forward end of this shaft n being provided with a squared end 0 which fits into the similarly shaped socket of the transmission shaft. The rear `end p of the shaft n is journaled in an axial passage in the shaft y. .\t thil forward und of thi` shaft; y. it is supported ou a ball-hcaring`r o iuount ed in lho front wall of Ihc casing f', this front uall heilig provided with a tubular extension l' which lits u ithiu thi rear end of the transmision cnw il. Hliilingi'l) hut nou-rotativclv mounted on shaft /i is a pinion x. on thiI rear face of which is a clutch incuihcr/ which is adapted to interlock with a clutch member u fixed on the forward faro of thiy gear 'l`ho pinion is adapted lo he shifted bach and forth on the shaft n by a forli r carried h'v a suitable levi-r.

It will hc observed that the intermediate .shaft n is adapted to he driven at` variable speeds by means of the usual variable-speed mcclinism in the transmission and that when the clutch members t and 'u are interlocked the propeller shaft ot' the vehicle will he driven in the usual manner and be subject to thi` usual ,variation in speed from the transmission mechanism. Then the propeller shaft is thus driven, the gears li: and ymy rotate idly. but.` b v disconnecting the clutch #nu and meshing the gear .v with the gear m. it will he seen that the propeller shaft is driven through thil ,fears in., if.' and j at a reduced speed, the reduction heiniiF determined bv the ratio of tho`grars. ln this wav. a reduction in the vehirle-driving mechanism ls obtained that is supplemental to the reduction that may he obtained bv means ot' the transmission alone, and, when this supplemental reducing gearingr is employed an important advantage is that the transmission may in many cases he run in high speed, thus materially increasimgr the eliiciency ot' the vehicle drive, it being well known that. especialhv in the Ford type of vehicle, the etliciency of the motor plant maintained at a higher degree while running on the high speed of the transmission.

B v sliding the gear s along the shaft fri to a point forward ot' the gear m and out, of mesh therewith, the gear s'may he brought into mesh with a gear 'w atlixed to a supplemental shaft :l: journaled in the casing c and adapted to he utilized for driving any suit:-k able appliance or mechanism other than the vehicle-wheel-driving devices, such, for instance, as a pump or other apparatus carried by the vehicle or inechanism located adjacent the vehicle. It will be seen that this auxiliary newer shaft w may be driven at varying speeds from the usual transmission of the vehicle, it being an essential 'characteristic of this invention tn thus' utilize the transmission to vuriuhly lr-ive this shaft The nature and scope of the invention havin been thus indieuud :md its preferred elnho .in'ient having been :specifically deseribed, what is claimed es new is:

l. An auxiliary trzmzsmission mechanism adapted to he installed adjacent the trans miseion gearinfr of an automobile, comprising :i short slmt adapted t0 he connected to the main drivelrshaft of the transmission so :is to be thereby veriably driven from the transmission, a inion slidahly but nonwotatively mounbe on Suid short shaft, means for clutching this short shaft to the propeller shaft of the vehicle, a ear on the forward end of said propeller s raft, and a neunten shaft provided with n pair of gears one of which meshes with the geur on `the forward end of the propeller Shaft and the other of which ie adapted tio mesh with the slidable Jinion on the short shaft when said clutch is out, for the ymrpofi'ey set forth.

2. The mechanism rersiled in claim 1, an auxiliary power shaft being arren ed par- :Lllel with seid short shft and 4being provided with a gear adapted to mesh with said inion when it is moved beyond its Compunion gear on the counter-shaft, for the purpose set forth.

ln testimony whereof I hereunto affix my signature. A
